ABSTRACT.
Three profiles were selected number 1,2 from EL-Brolis –Lake coast
and profile number 3 from Rashid where the samples are black sand and
every profile contain tow layer of surface and subsurface Physical and
chemical properties of the black sand are determined where the texture is
sand Soil reaction (pH) is alkaline, CaCO3% ranges from 0.55 to 1.10 % ,
organic matter varied from 1.74% to 4.04%, salinity of black sand is high
varied from 2.27 to 22.29 dSm-1. The cation and anion(mmolc/l ) followed
this order Cl - > Na+ > K+ >SO4
-- > Ca++> Mg++ > HCO3
- > CO3 -- . Total and
extractable of trace elements in international limits values and NPK in the
studied area varied form deficient to sufficient.
This study determine the concentration of trace elements ( Total
& extractable ) and find a relation between soil variables and the content
of trace elements.
